 DETAILED DESCRIPTION
In order to make objectives, technical details and advantages of the embodiments of the present disclosure more apparent, various embodiments of the present disclosure will be described below in details in connection with the drawings. However, those ordinarily skilled in the art may understand that, in the respective embodiments of the present disclosure, numerous technical details are set forth in order to provide a reader with a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and various changes and modifications based on the embodiments below. The embodiments below are divided for the convenience of description, and should not constitute any limitation to specific implementation manners of the present disclosure; and the embodiments may be combined with each other and mutually referred to without contradiction.
As shown in FIG. 1, a first embodiment of the present disclosure relates to a vehicle control method, with specific steps as follows.
Step 101: collecting a fingerprint image of a user.
Step 102: authenticating the user according to the fingerprint image; if the authentication succeeds, the process proceeds to step 103; and if the authentication fails, it returns to step 101.
Step 103: acquiring identity information of the user.
Step 104: acquiring a vehicle personalization parameter of the user according to the identity information of the user, and setting up the vehicle according to the vehicle personalization parameter.
In step 101, when finger touch is detected, the fingerprint image of the user is collected. Step 101 may be executed by a fingerprint sensor; and in an example, the fingerprint sensor is a capacitive sensor. The fingerprint sensor may be provided in the vehicle as needed, in a position such as a steering wheel and a console which is convenient for the user to touch.
In an example, as shown in FIG. 2, step 102 is specifically: judging whether there is a fingerprint template matching the fingerprint image in respective pre-stored fingerprint templates; if yes, it indicates that the authentication succeeds, and the process proceeds to step 103; if no, it indicates that the authentication fails, at which time the fingerprint image may be re-collected. Step 103 is specifically: acquiring, according to correspondence between the pre-stored fingerprint templates and identity information, identity information corresponding to the fingerprint template that matches the fingerprint image, as the identity information of the user. It should be noted that, the number of times the authentication fails may be recorded; if the number of times the authentication fails exceeds the preset number of times, the fingerprint image is no longer re-collected and the process ends. Wherein, the identity information of the user may be the user's name and account number, etc., and may be set as needed.
In an example, step 102 and step 103 may be executed by an independent microprocessor, at which time the respective fingerprint templates and identity information corresponding to the respective fingerprint templates may be pre-stored in the microprocessor. In this embodiment, a position for proving the microprocessor will not be limited, as long as it is communicatively connected with the fingerprint sensor.
Step 104 may be executed by a central control device of the vehicle; the central control device is pre-stored with correspondence between the identity information and the vehicle personalization parameter; and the central control device acquires the vehicle personalization parameter corresponding to the identity information of the user, according to the correspondence between the identity information and the vehicle personalization parameter. The vehicle personalization parameter may include parameters of various vehicle-mounted devices inside the vehicle, such as an air conditioning system, an electrically adjustable seat and an entertainment apparatus.
That is, the microprocessor outputs the identity information of the user to the central control device of the vehicle when the authentication succeeds; while outputs information that the authentication fails to the central control device when the authentication fails. The microprocessor may also output no information when the authentication fails.
It should be noted that in some example step 102 and step 103 may also be executed by the central control device of the vehicle, at which time the respective fingerprint templates and the identity information corresponding to the respective fingerprint templates may be pre-stored in the central control device.
As compared with existing technologies, in the embodiment of the present disclosure, the identity information of the user is acquired after the authentication of the user according to the fingerprint image succeeds, and the vehicle personalization parameter of the user is acquired according to the identity information, so as to implement personalized setting of the vehicle simply and quickly, which can facilitate sharing a vehicle among family members in most cases.
A second embodiment of the present disclosure relates to a vehicle control method. The second embodiment is substantially the same as the first embodiment, and a main difference is that: in the second embodiment of the present disclosure, a fingerprint sensor and a microprocessor are integrated together.
Specifically, the fingerprint sensor may be provided on an upper surface of the microprocessor, and then the fingerprint sensor and the microprocessor are packaged to form a whole by using a packaging technology, which is referred to as a fingerprint chip; and a fingerprint collection surface of the fingerprint sensor serves as a fingerprint collection surface of the fingerprint chip. The fingerprint chip has an independent fingerprint recognition function and is small in size, which may be mounted anywhere in the vehicle as needed.
A third embodiment of the present disclosure relates to a vehicle control method. The third embodiment is substantially the same as the second embodiment, and a main difference is that: in the third embodiment, a fingerprint chip is mounted on a start button of the vehicle, and when a user's finger presses the start button, the finger faces a fingerprint collection surface of a fingerprint sensor, so as to implement fingerprint-based one-button start. Wherein, the finger presses on a pressing surface of the start button, and the pressing surface may be a protective cover provided on the fingerprint collection surface, but it is not limited thereto.
FIG. 3 shows a flow chart of the vehicle control method according to the third embodiment, wherein, steps 201 to 204 are substantially the same as steps 101 to 104, so no details will be repeated here; and a difference is that, the method further includes step 205: notifying, by the microprocessor, the start controller of the vehicle to start the vehicle. That is, after the authentication succeeds, the microprocessor further notifies the start controller of the vehicle to start the vehicle.
In this embodiment, keyless vehicle startup and personalized setting can be completed based on a single fingerprint collection and authentication, which greatly reduces cumbersome operations for the owner of the vehicle. It should be noted that, after the authentication succeeds, vehicle startup and personalized setting are executed in no particular sequential order, that is, an execution sequence of step 205 and step 203 and step 204 shown in FIG. 3 is only an example, and it is not limited thereto.
In an example, the microprocessor may further determine whether to notify the start controller of the vehicle to start the vehicle in combination with other preset condition; for example, the microprocessor may notify the start controller of the vehicle to start the vehicle when detecting a brake signal and detecting that the authentication succeeds.
In an example, the microprocessor may further accumulate the number of times the authentication fails in step 202; when the number of times the authentication fails reaches the preset number of times, measures such as an alarm or a lock on the vehicle may be taken to improve safety of keyless vehicle start.
In an example, when receiving a command of enabling a fingerprint authentication function from the start controller, the microprocessor enters a fingerprint authentication mode; wherein, the command of enabling the fingerprint authentication function is generated by the start controller at least when it detects that the start button is pressed. FIG. 4 shows a schematic diagram of interaction of respective devices in a vehicle control system.
Specifically, when the finger presses down the start button, the start controller detects that the start button is pressed, and sends the command of enabling the fingerprint authentication function to the microprocessor; and in the example, the microprocessor is integrated in the fingerprint chip. When receiving the command of enabling the fingerprint authentication function, the microprocessor enters the fingerprint authentication mode. In the fingerprint authentication mode, the microprocessor authenticates the user according to a fingerprint image, and after the authentication succeeds, the microprocessor notifies the start controller of the vehicle to start the vehicle, so that the start controller, after receiving the notification, triggers an ignition device of the vehicle to ignite; in addition, the microprocessor acquires identity information of the user and sends the identity information of the user to a central control device; the central control device acquires a vehicle personalization parameter of the user according to the identity information of the user, and sets up the vehicle according to the vehicle personalization parameter.
When the finger presses down the start button, the finger faces the fingerprint collection surface of the fingerprint sensor, and the fingerprint sensor collects the fingerprint image; that is, the fingerprint sensor collects the fingerprint image without being affected by whether the microprocessor enters the fingerprint authentication mode; the fingerprint sensor executes an action of collecting the fingerprint image once detecting the finger; and the microprocessor authenticates the fingerprint image collected by the fingerprint sensor only after entering the fingerprint authentication mode. FIG. 4 is only schematic illustration, and a sequential order in which the fingerprint sensor collects the fingerprint image and the microcontroller enters the fingerprint authentication mode will not be limited.
Further, the microprocessor also has a fingerprint entry mode. Specifically, after receiving a command of enabling a fingerprint entry function, the microprocessor enters a fingerprint entry mode; in the fingerprint entry mode, the microprocessor generates a fingerprint template according to the fingerprint image, and establishes correspondence between the fingerprint template and the identity information of the user that is received through the central control device. In this embodiment, the user may input a fingerprint entry request to the central control device, and the central control device, when detecting the fingerprint entry request, sends the command of enabling the fingerprint entry function to the microprocessor.
Under normal circumstances, when the user needs to enter a fingerprint, the user firstly inputs the fingerprint entry request to the central control device through an input apparatus and inputs the identity information of the user; then, the user places his/her finger on the fingerprint sensor for fingerprint collection; so usually the fingerprint sensor collects the fingerprint image after the microprocessor enters the fingerprint entry mode. However, it should be noted that, the fingerprint sensor may collect the fingerprint image without being affected by whether the microprocessor has entered the fingerprint entry mode; that is, the fingerprint sensor collects the fingerprint image once detecting the finger.
A fourth embodiment of the present disclosure relates to a vehicle control method, the fourth embodiment is substantially the same as the third embodiment, and a main difference is that: in the fourth embodiment, when sending a command of enabling a fingerprint entry function to a microprocessor, a central control device disables a function for detecting, by a start controller, whether a start button is pressed.
FIG. 5 shows a flow chart of a microcontroller entering a fingerprint entry mode according to the fourth embodiment of the present disclosure. Specific steps are as follows:
Step 301: sending, by the central control device when detecting a fingerprint entry request, the command of enabling the fingerprint entry function to the microprocessor, so that the microprocessor enters the fingerprint entry mode.
That is, the microprocessor enters the fingerprint entry mode when receiving the command of enabling the fingerprint entry function.
Step 302: disabling, by the central control device, a function for detecting, by the start controller, whether the start button is pressed.
Step 303: collecting, by the fingerprint sensor, a fingerprint image of a user.
Step 304: generating, by the microprocessor, a fingerprint template according to the fingerprint image, and establishing correspondence between the fingerprint template and identity information of the user that is received through the central control device.
In this embodiment, a signal that the start button is pressed may be shielded during fingerprint entry, which can avoid an unexpected situation such as vehicle stalling that may be caused by the start button being pressed down during the fingerprint collection process.
A fifth embodiment of the present disclosure relates to a vehicle control method, the fifth embodiment is an improvement based on any one of the first embodiment to the fourth embodiment, and a main improvement is that: in the fifth embodiment, live detection may further be performed, and when the detection succeeds, a user is authenticated according to a fingerprint image.
FIG. 6 is a flow chart of a vehicle control method according to the fifth embodiment of the present disclosure, where steps 402 to 405 are substantially the same as steps 101 to 104, so no details will be repeated here; and a difference is that, the method further includes:
Step 401: performing live detection through an infrared sensor; if the detection succeeds, the process proceeds to step 402; and if the detection fails, it returns to step 401. Wherein, the number of times the live detection fails may be recorded; and if the number of times reaches a preset value, it may be considered that the authentication fails.
Specifically, the infrared sensor collects an infrared image of a finger, and the microprocessor performs live recognition on the finger based on the infrared image; if it is recognized as a live finger, the microprocessor authenticates the fingerprint image collected by a fingerprint sensor. That is, it may be understood as that, after entering a fingerprint authentication mode, the microprocessor firstly performs live recognition on the finger based on the infrared image, and after the live detection succeeds, authenticates the fingerprint image collected by the fingerprint sensor.
The infrared sensor may be integrated in the fingerprint chip, and step 401 is executed by the microprocessor, that is, the microprocessor performs live detection through the infrared sensor integrated in the fingerprint chip. The fingerprint chip further has a live detection function, and fingerprint authentication is performed only after the live detection succeeds, which, thus, can avoid a malicious person from using a fake finger to start the vehicle when implementing fingerprint-based keyless startup, so as to improve safety of fingerprint-based one-button vehicle startup.
In this embodiment, after the live detection function is added, the microprocessor, only in a case where the live detection succeeds and the fingerprint image authentication succeeds, determines that the user authentication succeeds, and outputs the identity information of the user to a central control device of the vehicle; while in a case where the live detection fails or the fingerprint image authentication fails, determines that the user authentication fails, and outputs information that the authentication fails to the central control device. That is, regardless of whether or not the live detection function is added, a result output by the microprocessor is either the identity information of the user or the information that the authentication fails.
The steps of the above various methods are divided only for clarity of description; when implemented, the steps may be merged to one step or some steps may be split into a plurality of steps, which are all within the protection scope of this patent as long as they include a same logical relationship; additions of insignificant modifications or introductions of insignificant design to algorithms or processes without changing core design of the algorithms and processes, are all within the protection scope of this patent.

In addition, an air conditioning system, an electrically adjustable seat, and a vehicle-mounted entertainment device shown in FIG. 8 are all vehicle-mounted devices in the vehicle, which are merely illustrative here and not limited thereto; and the central control device may perform personalized setting on the vehicle-mounted devices according to vehicle personalization parameters of the user.
